WIN EVERY TRADE.
BUILD A HUGE
INVENTORY.

JB Trade Scanner reads the Jailbreak trade window, weighs value, demand and item type, and tells you it's a BIG WIN before you hit Ready. So every trade grows your inventory.

How it works

THREE SECONDS. ONE KEY.

No typing item names, no alt-tabbing to a value list.

STEP 1

OPEN A TRADE

Trade like normal in Jailbreak. The app finds the trade window by itself, at any resolution.

STEP 2

PRESS F8

It reads every item on both sides, including Hyper colors and levels, and prices them with JBValues values.

STEP 3

SEE THE VERDICT

BIG WIN, WIN, FAIR, LOSS or BIG LOSS, right on the in-game tracker, with warnings if something's off.

Real trade power

A "WIN" ON PAPER CAN BE A LOSS.

Value lists treat $10M of tires like $10M of car. Real traders don't. JB Trade Scanner weighs every item by value × demand × item type, so you see what your side is really worth.

  • Cars count the most. They're the easiest items to trade on.
  • Low-demand items count less. They're hard to trade away later.
  • Warnings for downgrades without overpay, dropping values and commonly duped items.

In-game tracker: BIG WIN, your value vs theirs, trade power, demand comparison and what you get
The in-game tracker

RIGHT ON TOP OF ROBLOX.

A small panel that stays over the game while you trade. Drag it anywhere, collapse it to a strip, and it's there every time you press F8.

  • Your value vs theirs, and trade power for both sides
  • Demand comparison and what item types you'd get
  • Never steals focus from the game

  • No injection. It never touches Roblox's files or process.
  • No memory reading. Only the pixels you can already see.
  • No automation. It never clicks, types or trades for you.
  • No passwords. Sign in with Google, no license keys to lose.

FAQ

QUESTIONS

Can I get banned for using it?

JB Trade Scanner doesn't inject into Roblox, read its memory or automate anything. It only takes screenshots, the same as the Snipping Tool or a recording app. It never interacts with the game.

Where do the values come from?

From the public JBValues.com value list. The app updates them automatically and keeps a copy so it still works offline.

Why is my "win" a loss?

Because not all value is equal. A car is much easier to trade on than tires or furniture of the same value, and low-demand items are hard to get rid of. The app shows both: the raw value result and the real trade power result.

Does it work on my screen size?

Yes. It finds the trade window by itself at any resolution. If it ever can't, you can drag a box around the trade window once and it remembers it.

How do I unlock the app after buying?

No license keys. Sign in with Google on this website and buy. Then click Sign in with Google in the app and use the same account. It unlocks on up to 3 PCs.

Can I get a refund?

Yes. If it doesn't work on your PC, email us within 14 days for a full refund. See the refund policy.

Does it work on Mac, mobile or console?

No, it's a Windows 10 / 11 app for playing Roblox on PC.
